Insights on quantum mechanics

first_imgFor the first time, physicists at Harvard University have tracked individual atoms in a gas cooled to extreme temperatures as the particles reorganized into a crystal, a process driven by quantum mechanics. The research, described in the journal Science, opens new possibilities for particle-by-particle study and engineering of artificial quantum materials.“Much of modern technology is driven by engineering materials with novel properties, and the bizarre world of quantum mechanics can contribute to this engineering toolbox,” said Markus Greiner, an assistant professor of physics at Harvard, who led the research team. “For example, quantum materials could be used to turn heat into electricity, or in cables that transport electricity very efficiently in a power grid.”“The challenge in understanding the behavior of such materials is that although we have many ideas about how they might work, we lack the tools to verify these theories by looking at and manipulating these materials at the most basic atomic level,” Greiner said. “This is the problem we have set out to tackle.”To circumvent the challenges of studying such materials, Greiner and his colleagues created an artificial quantum material, a cold gas of rubidium atoms moving in a lattice made of light. This pancake-shaped cloud, known as a Bose-Einstein condensate, allowed them to study the physics of quantum materials at a much larger scale, essentially simulating what happens in a real material.The physicists watched individual atoms participate in a dramatic collective transition between two states of matter, similar to the transition that happens when water freezes into ice. But this transition was driven not by temperature but by the researchers’ manipulation of interactions between the atoms.“We counted the number of atoms at each site of the lattice,” said co-author Waseem Bakr, a graduate student in Harvard’s Department of Physics. “When the interactions between the atoms are weak, the number of atoms varies significantly in different sites due to uncertainty that is intrinsic to quantum mechanics. When we increase the interactions, these fluctuations vanish, and the atoms arrange into an almost perfect crystal.”Such a transition from a superfluid state — in which particles can move with no resistance — to an insulating Mott state — where the atoms can no longer move — was first observed by Greiner and colleagues in 2001. However, a quantum gas microscope developed last year by Greiner’s group now allows observation of individual atoms as they undergo this transition.“This microscope is a versatile tool which should be able to shed light on many other phenomena related to quantum materials, such as magnetic materials,” Greiner said. “It could even be used for computations that require enormous resources on current computers.”While a simulation similar to the current experiment could, in principle, be carried out on a computer, Greiner said that such an approach would quickly become infeasible for a system with more than a few dozen atoms.Greiner and Bakr’s co-authors in Harvard’s Department of Physics and at the Harvard-MIT Center for Ultracold Atoms are Amy Peng, Eric Tai, Ruichao Ma, Jonathan Simon, Jonathon Gillen, and Lode Pollet, as well as Simon Foelling of Harvard and Ludwig-Maximilians-Universität in Munich. Their work was supported by the Army Research Office, the Defense Advanced Research Projects Agency, the Air Force Office of Scientific Research, the National Science Foundation, the Swiss National Science Foundation, and the Alfred P. Sloan Foundation.last_img read more

They’re the Top! Broadway.com Names the Best Shows of 2014

first_img View Comments HEDWIG AND THE ANGRY INCH Who knew a show about an East German transgender singer dealing with a botched sex-change operation and a broken heart would conquer Broadway? That’s exactly what Hedwig and the Angry Inch did. The ‘90s downtown sensation was reborn as a refreshing star vehicle with tourist appeal. What makes it so alluring? Is it the high-wattage headliners? The kick-ass score? The oddball storyline? The slick production? Who cares! Hedwig makes us scream like teenyboppers at an Elvis concert. We are forever grateful we live in this wicked little town and get to see it over and over again. YOU CAN’T TAKE IT WITH YOU Forget the idea that “all happy families are alike,” there’s nobody like the loving but ludicrous Sycamore family in You Can’t Take It With You. Whether they’re poorly pirouetting, setting off fireworks or serving up follow-your-heart philosophy with a side of Russian royalty, you can’t help but fall for this cray-cray clan and their eclectic crowd of hangers-on. It’s no small thing to see this Kaufman and Hart farce acted with comic perfection (led by the indomitable James Earl Jones): there’s a huge cast and many threads to follow, yet this production comes together like a delectable soufflé. Broadway offered up 39 shows in 2014, but the Broadway.com staff only chooses five as the best of the year. After much consideration (not to mention hours at the theater taking it all in!), we’ve finally made our decision. Take a look at our favorites below. ALADDIN Hand it to Disney to grant our wish for a splashy musical comedy that makes both kids and grown-ups giddy with the magic of theater. Aladdin shortchanges no one: it’s a glittering sugar high of a musical, complete with gorgeous vocals from stars Adam Jacobs and Courtney Reed, a bravura turn from Tony winner James Monroe Iglehart as the Genie, eye-popping visuals (including the no-idea-how-they-do-it magic carpet ride) and a story with heart. There’s something to be said for hearing seven-year-olds belly laugh as they’re introduced to a whole new world…Broadway. Bravo, Aladdin! OF MICE AND MEN Sure, audiences probably remembered the story from English class, but Anna D. Shapiro’s impeccably directed production of Of Mice and Men was transporting whether you knew the plot beforehand or not. James Franco and Chris O’Dowd offered more than just star power with their nuanced performances as migrant farm workers deferring their dreams during the Great Depression. The play’s themes of loneliness and isolation were on display against the starry nights of Steinbeck’s Salinas Valley. This was not a reimagining but rather a straight-up revival produced with deft and dignified sparseness. THE CURIOUS INCIDENT OF THE DOG IN THE NIGHT-TIME Curious Incident took us somewhere we didn’t even know we wanted to go: the mind of 15-year-old boy on the high-functioning end of the autism spectrum. Under the inventive direction of Marianne Elliott and her dazzling design team, this play (based on a bestselling novel) presents an obstacle-ridden journey the main character (impressive newcomer Alex Sharp) and the audience navigates together. In doing so, it manages to create order in an overwhelming world while being quirky, clever and insightful about the ties that bind and the unexpected gift of a child’s ability to truly see everything.last_img read more

Hurley family ready to witness history

first_img(WBNG) — Douglas Hurley’s family says they are excited and proud ahead of the historic SpaceX launch. “It’s great to see everybody is excited about it, not everybody has this historic event happening, a person from our community doing this,” said Dean. Dean and his family said they are grateful to see the support from the Southern Tier as Doug makes history. “It’s not just about watching it it’s about feeling it, that’s the best way I can decribe the first two launches,” said Jolene. “He sent us a text today (Wednesday) that said ‘you guys have fun today’ and I sent him a text back that said ‘you have fun too,’ and he said ‘oh yeah!'” The family was present at Doug’s first two launches, in 2009 and 2011. Dean said it doesn’t get old. “This is such a historic event, you just can’t put it in words.” While the family mostly feels excitement, Jolene said “the inherent risk of what he does can be a little scary, as his family.” Jolene also said Doug was calm ahead of the launch, saying he’s “even-keeled, all the time.”center_img Click here to watch the launch. When the first attempt was scrubbed Wednesday due to inclement weather, Dean said they would remain in Florida for today’s launch attempt. Doug’s brother Dean Hurley traveled from Vestal along with his wife Jolene, and their two children to support Doug, an Apalachin native. Catching up with them Wednesday, the family said it’s a surreal experience. Ahead of Wednesday’s attempt, Dean shared a text Doug sent him.

India to ‘reimagine’ streets for walkers, cyclists after coronavirus

first_imgAuthorities in India – home to more than half the 10 most polluted cities in the World Air Quality Report index – can also use unclaimed and under-utilized public spaces to increase walkability, it added.Pedestrianization of streets and market places is “not only feasible, but the only viable option”, and key to restoring safety, vibrancy and livability in communities, said Jaya Dhindaw, director of urban planning at research firm WRI India.”For the longest time, pedestrian and cycling infrastructure has been the lowest priority despite the fact that non-motorized transport is affordable, people-friendly and offers huge social, economic and environmental benefits,” she said on Wednesday.”What seems like a necessary step to aid movement during the health crisis definitely has the potential to re-wire cities’ mobility trends,” she told the Thomson Reuters Foundation.Under India’s Smart Cities program that aims to make 100 urban centers more livable and sustainable, some cities had already been promoting public transit and bicycle lanes.The southern Indian city of Chennai has carved out more than 100 km (62 miles) of pedestrian-friendly streets, the urban affairs ministry noted.Chennai’s efforts paid off during the lockdown, said Raj Cherubal, chief executive of Chennai Smart City Ltd.”We should use the coronavirus as an excuse to rejig our streets and our approach to public transit,” he said.”India doesn’t have a choice but to do this to limit emissions, and curb congestion and pollution.”With India grappling with an economic downturn caused by the pandemic, authorities facing shrinking budgets will need to be innovative in their mobility plans, Dhindaw noted.”Small-ticket items like non-motorized transport infrastructure expansion and improvements that got left out in the scramble for metro and light-rail will now see renewed interest,” she said.”In the long term, it will lead to more equitable and inclusive cities.” “COVID-19 presents us with an opportunity to reimagine streets for people,” Durga Shanker Mishra, the ministry’s secretary, said in a statement last week.”As cities look to ease the lockdown and provide safe, affordable and equitable modes of transport, the need for pedestrianization of market spaces through walking- and cycling-friendly cities is of utmost importance,” he added.While cities worldwide ease lockdown restrictions, some are closing roads to vehicles, adding bicycle lanes, widening pavements and handing over parking spaces to cafes.In India, authorities should consult with vendors and residents on immediate measures such as barricades, road closures and repurposing of parking spaces, the urban affairs ministry said. Topics :center_img India will make its streets and markets more accessible to pedestrians and cyclists as it emerges from one of the world’s strictest coronavirus lockdowns, a move urgently needed to curb pollution and improve livability, urban experts said.An advisory issued by the Ministry of Housing and Urban Affairs recommended the pedestrianization of up to three markets in each city, and adding more bicycle lanes.City authorities must select the markets by June 30, and begin implementing short-term measures from Oct. 1, it said.last_img read more

Large homes see auction success, led by designer properties and those in education precincts

first_imgGreat entertainment space in the back yard. REAL ESTATE: 71 Moreton Street New Farm. Picture: realestate.com.auDESIGNER Queensland homes — including one with an outdoor fireplace — and properties in popular education precincts had the best success at Brisbane auctions — but agents are treading carefully.A stunning four bedroom, three bathroom, triple car space house at 71 Moreton Street, New Farm, went under contract after selling under the hammer on Saturday for a tidy $2.76 million.The 1920s Queenslander home, whose charms included an outdoor living zone complete with traditional fireplace, seemed to have struck the right note with the buyers, who were empty nesters looking to move up from Sydney.Agent Ivo Kornel of Belle Property marketed it as “a perfect synergy of classical and new age” after a renovation project gave it a major overhaul two years ago.It had five registered bidders, three put their hand up during bidding and the interstate buyers were successful. 22 Kentwell Place, Wishart Qld 4122. Picture: Realestate.com.au A traditional facade belies what’s inside this multimillion-dollar home. The back veranda has shutters for privacy and shade.Being close to leading private schools like Brisbane Boys College and moments from the University of Queensland, it was “pretty hotly contested”, he said.‘Rokeby Green’ — on a 467sq m title including courtyards and garage — is in the suburb adjacent to St Lucia where the University of Queensland main campus is located.Also successful under the hammer on the weekend was 22 Kentwell Place, Wishart, which was billed the suburb’s “ultimate family home” and sold for $990,000. The property was in the popular Mansfield State High School catchment zone — an independent public, coeducational school of over 2200 students. A modern extension and lap pool create a different feel in the backyard.More from newsParks and wildlife the new lust-haves post coronavirus1 day agoNoosa’s best beachfront penthouse is about to hit the market1 day ago“It was a great campaign, great numbers but a little thin on the ground in terms of who puts their hands up,” Mr Kornel said. “You can have 100 guys on the ground, but not putting their hand up. This was a success because we had a buyer.”He said auctions around New Farm were finding bidders increasingly thin on the ground.“Not a huge amount are putting their hand up. A lot of people say it’s because it’s the top of the market. A lot of buyers being priced out of the market … So we’ve got to pick and choose auctions carefully. Sale by negotiation is working really, really well too.”A four bedroom, three bathroom freestanding home at 1/20 Rokeby Terrace, Taringa, was also successful under the hammer, going for $810,000.“It’s a body corporate, more of a townhouse type set up,” said agent Elliot Dean of Dean Property Team.“There were five registered bidders, 35 people in attendance, three of the five were bidding. It was a good auction, a lot of action, bidding started at $550,000 and stopped at $810,000.” 1/20 Rokeby Terrace, Taringa Qld 4068. Picture: Realestate.com.au A large kitchen and polished floorboards perfect for a modern family. The living area has double height ceilings.Agent Lucky Ramya Tennekoon of Stellario Realty Group Wishart had it on the market as a luxury property “in a serene and exclusive pocket” of the suburb. Among its features was a pool, alfresco entertaining zone, an 800sq m block, side gate access for a boat or caravan to park on-site, and a 5kw, 16 panel solar electricity and hot water system “which cuts your electricity bill by a huge percentage”.last_img read more

The right property can sell under the hammer even at a quiet time of year

first_imgAuctioneer Haesley Cush said the market was performing well during a traditionally quiet time of the year. Picture: AAP/David ClarkWith bidding opening quite low in the $50,000s, it rose quickly and was called on the market around $700,000. It was then that the bidders got creative with numbers fluctuating between $10,000 to as obscure as $771.00 and $777.00 rises. I was up for the challenge and it only added to the excitement.The property eventually sold for $777,000 to huge applause for the well entertained crowd.Seeing the perfect game in sight I ducked around the corner to call the auction of a replica Queenslander at 33 Park Street. The backyard was decorated with bidders all preparing their game plans as I called for an opening bid. Of the nine registered bidders, five raised their cards as the price rose from $700,000 to $900,000, where again the bidding stalled.A lovely young couple with a baby in arms, raised their bid to $940,000 where the property was announced on the market and ultimately sold!Heading home, having crisscrossed the city, I reflected that while Brisbane can go quiet during winter the day showed that there are buyers in the market. It’s a wonderful sign for the Brisbane real estate market heading into the new year. 23 Bay St, Kedron sold under the hammer.LAST Saturday, with the Akubra on the dashboard, I set off to call four Brisbane-based auctions.The June and July period can be quiet so I was thrilled to see that all properties were stacked with bidders prior to the day.My first stop was 23 Bay Street Kedron. The property was a contemporary home in a quiet enclave in Kedron nestled close to the new Coles and schools. There were eight registered bidders and roughly 50 locals gathered in the open back yard to ultimately watch two couples battle it out for ownership.One was a mature couple, roughly in their fifties and the other was a young couple and if I was guessing I’d say in their twenties. The final price of $1,351,000 saw the young couple victorious and me off to the next auction.I jumped straight in the tunnel and dipped below the city on my way to Sirius Street Cooparoo. For sale was a cracking home in one of the region’s most loved streets. The house was beautifully presented and the owners were obviously quite popular with their neighbours because a huge crowd was in attendance to watch the sale unfold.There were nine bidders registered and with bidding opening at $795,000, it quickly rose through the million dollar price on its way to $1,190,000 before I had to pause proceedings to get some instructions.After some good spirited negotiating and flexibility from all parties the property was announced on the market and sold for $1,260,000!More from newsNew apartments released at idyllic retirement community Samford Grove Presented by Parks and wildlife the new lust-haves post coronavirus17 hours agoWith two contracts in the briefcase I finished the day at Kelvin Grove with two auctions, in neighbouring streets. The first was a renovator at 11 Gebbie Street. These renovators are the hottest property in the Brisbane market at the moment and the interest certainly supported the hype.last_img read more

Palm Beach County’s Face Mask Order Takes Effect Thursday

first_imgPeople in Palm Beach County will be required to wear masks in public beginning on Thursday morning.The rules, which the county commission approved unanimously on Tuesday, will take effect at 12:01 a.m. Thursday.The county’s attorney was still reviewing an order outlining the requirements late Wednesday. However, these are the major points:-Facial coverings must be worn indoors, including stores and restaurants, and they must be worn outdoors where social distancing is not possible.-Plastic facial shields, without masks, are permitted.-There are exemptions for people with a medical condition such as asthma; people who are exercising and still social distancing; while eating and drinking; and for children under age 2.Protect yourself & others from #COVID19. Practice #socialdistancing & stay at least 6 feet away from other people. Wear a face covering so you don’t spread germs. Face coverings should not be used on children under 2.For more tips, visit https://t.co/DdkHbqXBwC pic.twitter.com/SNsUvUyqzf— Palm Beach County (@pbcgov) June 24, 2020 -Violators can be fined $250 for the first violation and $500 for each additional violation. Unlike Miami-Dade and Broward counties, the county’s order does not make any mention of jail.-The draft ordinance also does not include penalties for businesses that fail to comply, but they still must follow state orders.“The county’s emphasis will be education, education, education,” said Mayor Dave Kerner. “Wearing a mask is an act of kindness” to protect people around you, he said.The Florida Department of Health reported on Wednesday that 109,014 people statewide have tested positive for COVID-19 since the pandemic began.Palm Beach County had 356 new cases reported Wednesday, bringing its total to 11,536 cases. In addition 495 people have died in the county as a result of the virus.Medical officials told commissioners on Tuesday that facial coverings are not dangerous to people wearing them, and could prevent someone who is unaware they have the virus from infecting others.last_img read more
